NASA's PUFFINS mission, led by Dr. Ramya Manjunath Anche, an Indian-origin scientist from Bengaluru, aims to study interstellar dust to better understand the formation of stars, planets, and the potential for life beyond Earth. The mission, which has received a $20 million award under NASA's Astrophysics Pioneers program, will launch in 2030 and use a small satellite equipped with a 10-inch telescope to observe ultraviolet light from approximately 70 stars. By analyzing how this light interacts with interstellar dust grains, scientists hope to map the smallest dust particles, which are typically less than one micron in size. These grains, categorized as silicates (resembling sand) or carbonaceous (similar to soot), play a crucial role in the formation of planetary systems. Dr. Anche emphasizes that dust is fundamental to understanding the origins of life, stating, 'You cannot separate the question of life in the universe from the question of dust.' The mission will employ polarimetry, measuring the polarization of light, to distinguish between different types of dust grains. This technique, not used for this purpose in three decades, will help scientists understand how dust affects observations of the cosmic microwave background, a key area for studying the early universe. Dr. Anche's interest in astronomy was sparked by Kalpana Chawla, the Indian-born astronaut, and she hopes the PUFFINS mission will contribute to answering fundamental questions about the universe's evolution, planetary formation, and the potential for extraterrestrial life. The research could significantly enhance astronomers' ability to search for life beyond Earth by providing detailed insights into the building blocks of planetary systems.

The yellowish “lower haze” in Venus’s atmosphere was detected by the Venera and Pioneer Venus spacecraft as early as the 1970s. They were among the first spacecraft to transmit images of the planet to Earth, but the haze’s origin remained a mystery for decades. Scientists have now determined what causes the phenomenon. The study found […] Post A 50-Year Mystery: Scientists Have Identified the True Nature of Venus’s Mysterious Haze at Root-Nation.com.

A physical model show that iron dust and sulfuric acid create the right properties.

Cosmic Dust Solves Venus Haze Mystery

Unlike Earth, the Moon has preserved radioactive debris from supernovae dating back 80–100 million years. The surface of our planet’s natural satellite conceals radioactive remnants of ancient stellar explosions, resembling glitter mixed with cosmic dust. An innovative computer model has allowed experts to distinguish microscopic dust from supernova explosions from ordinary lunar soil. This transforms […] Post A Radioactive Trail in Space: A Way to Decode Stardust on the Moon Has Been Found at Root-Nation.com.
